Carrying a dog in your handbag is cool again. Honestly. Not the runty-looking rat-dogs of the Paris Hilton days of yore, though: this time, we're talking mutts with a bit of heft. Well, Harvey Nichols is.

The store's new spring campaign, called "The New Breed" (ho ho, very clever) features three sizeable hounds being toted in fancy handbags: Spud, the British bulldog, is poking out of a yellow 3.1 Phillip Lim; Pepper, a Staffordshire Bull Terrier, looks stoically on in his green Marc by Marc Jacobs; and Dozer, an English Bull Terrier, peers from a blue Sophie Hulme. (Toting a bulldog = the new bicep workout.)

The campaign was shot by Miles Aldridge, who's worked with American Vogue and Numéro, and styled by Harry Lambert, who does the Topman ads. They'll go into print, including in the store's own free magazine, and appear across the London Underground and bus stops within Zone 1, as well as black cabs, from today. And you'll get special "doggy-bag" packaging with every purchase at the Knightsbridge flagship.
